Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 7.6 range ? - ? cm
Max length : 16.1 cm TL 雄魚/尚未辨別雌雄; (Ref. 118626); common length : 9.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5217); 最大體重: 19.30 g (Ref. 118626)
背棘 (總數): 0; 臀棘 0; 臀鰭軟條: 38 - 44. Belly with 16 or 17 (rarely 19) + 9 to 11, total 26 to 28 (rarely 30) scutes. Lower jaw not strongly projecting; strong conical teeth in both jaws, continued as large and small teeth along maxilla blade. Easily recognized by large, canine-like teeth in both jaws (Ref. 26938). Dorsal fin origin behind midpoint of body; anal fin moderately long, its origin below or in front of dorsal fin origin.
腹面有 16 或者 17(很少地 19)+9 到 11, 總計 26 到 28(很少地 30)個鱗甲。 下頜不是強烈突出; 強的錐形齒雙顎內，當大而小的齒沿著顎骨葉片，繼續。 容易地雙顎內辨識特徵為大又像犬齒一樣的齒了。 (參考文獻 26938) 身體的背鰭起點中點後面; 臀鰭中等長度的, 在背鰭起點下面或前面的它的起源。
Occurs in coastal areas, but also in lagoons and off river mouths, perhaps entering water of lowered salinity (Ref. 12225). In Southwestern Atlantic preys on proportionally large clupeoid fishes and caridean shrimps. Fishes are distinctively folded in the stomachs of this herring, in about 90% of the cases with their heads and tails pointing head-wards the predator. This herring stands out as the only small-sized species among the predaceous fish-eating clupeiforms. The well developed canine-like teeth are likely related to a piscivorous diet and may play a role in the folding and orientation of fish during prey handling and swallowing (Ref. 51383). Spawns during the northern winter (Ref. 37032).
出現於沿岸區域, 也在潟湖與河口外中, 也許進入低鹽度的水域.(參考文獻 12225) 在大西洋西南部捕食比例大的鯡魚與槍蝦。 魚特殊地在這一個鯡魚的腹部被摺疊,在大約 90% 的情況和他們的頭部與尾部指出頭部-守護掠食者。 這一個鯡魚突出如在食肉的吃魚的 clupeiforms 之中的唯一體型小種。 發展良好的像犬齒一樣的齒是與或許有關的一個以魚為食的食性而且可能扮演一個角色在那折疊的與在操作和吞的獵物的時候魚的方位.(參考文獻 51383) 產卵於北方的冬天。 (參考文獻 37032)
